How do I cover up the ugly butt-end of a fan? - Page 2

post #11 of 19
Define "work." biggrin.gif

In theory it should help avoid turbulence caused by the flat back of fan as air blows past it. In reality on these small fans it would be very hard to verify or prove.

It's just a matter of scale.

The impact you'd feel from a 6m 700kg Patriot would be many orders of magnitude more painful than the impact from a 12cm 50g dart.

But you'd not fail to notice the dart biggrin.gif .
